NITED *rares EBENEZER OLIVER, OF NEWT YORK, N. Y., ASSIGNOR TO W.SHEPARD ESTEY, OF JERSEY CITY, NEW JERSEY.

RIDDLE OR SIEVE.

SPECIFICATION forming part of Letters Patent No. 378,458, dated February28, 1888.

Application iiled October 14, 1886. Serial No. 216,212. (No model.)

To @ZZ whom t may concern,.-

Be it known that I, EBENEZER OLIVER, of the city and State of New York,have invented an Improvement in Riddles or Sieves, of which thefollowing is a specification.

InLetters Patent No. 234,605, granted to me, a riddle or sieve is setforth in which the woven wire is surrounded by a strip of sheet metalfolded to retain the ends ofthe Wires.

In my present invention I make use of a similar screen; but I constructthe Wooden hoops or body in such a manner as to obtain greater strength,and to prevent the splitting of the hoop that surrounds the screen, ashas sometimes happened.

In the drawings, Figure 1 is a vertical section ofthe screen or riddle.Fig. 2 is an elevation of the same, and Fig. 3 is a partial plan viewshowing the body-hoops.

The Woven-wire screen A is surrounded by the band B of sheet metal,folded in substantially the manner set forth in aforesaid patent, andthere is a body-hoop, O, and an inner hoop, D, forming a ledge, uponwhich the edges of the screen rest, and there is a cylindrical body,

E, within the bodyhoop O and resting at its lower edge upon the band B.

Heretofore the cylindrical body E has been connected by metallic strapsto the body-hoop C; but I have found in practice that this bodyhoop C isliableto split horizontally near the line ofthe screen A. To avoid thisdifficulty I make use of the clampingbands H, ol' hoopiron or othermetal, placed at suitable intervals around the body-hoop O. The upperend .of each clamping-band H is folded over to inclose the upper edge ofthe body-hoop O, and the band is passed down outside the bodyhoop, andit is bent inwardly below the lower edge of the body-hoop C and theinner hoop, D, and the end of the clampingband is bent up Within thisinner hoop, D, whereby each clamping-band becomes a rigid clip toconnect the inner hoop, D, to the body-hoop O, and at the same time tostrengthen these Wooden hoops, so that they will not separate from eachother or be liable to slip; and I find that usually it is only necessaryto retain the cylindrical body E in its place by friction, because thesame can Iit sufliciently tight to remain in its place; and it can beeasily removed for inserting a new screen or for changing the screen forone of a different mesh, and in use these parts are not liable toseparate, because the hands are usually placed beneath the bodyhoop inhandling the screen.

Wire braces or stays L are provided, as usual, beneath the sieve A.

I claim as my invention-- l. The combination, with the screen or riddleA, of the body-hoop O and inner hoop, D, and the vertical metallicclamping-bands H, inclosing the top edge of the body-hoop O and thebottom edges of the body and inner hoops, and the removable cylindricalbody E, substantially as specified.

2. The combination, with the screen A, having a metallic band around itsedge, of the inner hoop, D, upon which the edges of the screen rest, thebody-hoop C, inclosing the screen and the inner hoop, the verticalmetallic clampingbands H, inclosing the top edge of the body-hoop C andthe bottom edges of the body and inner hoops C D, and the removablecylindrical body E, Within the body-hoop C, and resting at its loweredge upon the band B of the screen, substantially as set forth.

Signed by me this 11th day of October, A. D. 1886.

E. OLIVER.
